To all whom 'it may concern: ,i

Be it known that I, AARON. FU'r'rERMAN, a America, residing at New York, iii the borouvli of the Bronx, county and State of New Yirk, have invented certain. new and useful Improvements in Welding-Tools, of which the following is a specificationl This invention relates to an improved welding oolinwhi'ch a mixture ofacetylene and oxygen 1s employed. v j

The novel features of the invention will be hereinafter described and claimed.

In the acconipanyingdrawings, Figure 1 representsa side-elevation of my improved welding tool, Fig-2 is a section on line 2-2,

Fig. 1, Fig. 3 is .a vertical transverse section `throlgh the mixing nozzle,`on line 3, 3, Fig. `l, an

Fig. 4 is a vertical transverse section on line 4,4, Fig. 3.

Similar letters of referenceindicate corre spending parts.

Referring to the drawings, a. represents vthe acetylene tube, which is Vprovided with a stopcock'al inear its ingoi'ng end, and which -is connected by a `suitable hose a2 with an acetylene generator of any ,approved con-- struction, so that the acetylene gas is supplied under pressure to the supply-tube a.-

.Near the stopcock a1 is arranged a cylindrical receiver b, which is -illed With asbestos fiber for retarding the flow of acetylene gas. The receiver b is connected by the tubea and V a nipple la", with the cylindrical main-portion of -a nozzle d, to the lower end of which is screwed a nozzle n, of which a number are provided, havino' different sizes of openings so as toobtain ames of larger and smaller size, according to the metallic objects 'which are welded together.

A hose e is connected with a fountain con-I taining oxygew under ressure, and with tubesections,e, e2 Whic lead to a stuiingbox c3 at the up er part of the cylindrical body of the'nozz e d, the oxygen'being supplied through a central opening oat the inf ner end of the nozzle, while the acetylene is l supplied through a side-opening o1 in the nozzle. The acetylene-suppl tube is madelarger than the'oxygen-supp y tube, so that a larger quantity of acetylene is conducted tothe nozzle than the quantity of oxy en supplied. The oxygen tube c2 is provi ed with a stopcock e* so as to regulate the supply of oxygen. The oxygen-supply tube e is supported in standards f, which are atat the ends of the latter.

The upper ends of the standards f are extended aboye the oxygen-supply tube e and Itached to hubs f1 onthe tubular receiver 1.

one is provided with an eye, while the other standard is provided with .a forked end f`2 forvinserting an auxiliary supplytube g, which is curved in' downward direction near `the nozzle n so as to terminate in a smaller nozzle g1 adjacent to the nozzle n in order to supply an independent supply of oxygen to the acetylene-oxygen fiaine emit-ted through the discharge-opening in. the nozzle-end. The auxiliary oxygen-supply tube g is held 'in the forked end f2 by a set-screw gg so that the` location of the nozzle g with respect to the'nozzle n can' be adjusted, the opposite end of the auxiliary tube g being provided adjacent the other standard f with a swiveled vnipple g3 into which is screwed a connecting 'hose g4 for the oxygen.

Thejend .of the auxiliary tube g is curved in sueltalmanner that it passes sidewise of the acetylene-supline with In testimony, that I claim the foregoing' as my invention, I have signed my naine in presence of two subscribing witnesses.
